Describe the elements of a VoIP Dial Plan Design

Dial-Plan Components Fundamental VoIP network must have the following features: Local dial-peers to map phone numbers to a physical port Network dial-peers to map phone numbers to an IP address The ability to strip and add digits Number expansion

Dial Peer Types POTS or Local Dial Peers - means that the dial peer associates a physical voice port with a local telephone device. VoIP Dial Peers – On a packet voice network, these dial-peers point to specific devices

Module Objective 5 Configure Voice Interface Cards (VICs) to place VoIP Calls

A Voice Interface Card (VIC)

Various VIC Configurations

Voice Port Numbering Cisco IOS configuration commands identify voice ports in the form router-slot/voice-slot/VIC-port You can use the show voice port command to show the port numbers of the interface installed on your router.

VoIP Configuration Scenario

Some VoIP Configuration Commands dial-peer voice destination-pattern port session target

Step1 – Local Dial Peers To route a received voice call to the right destination, the router needs to know which telephone number belongs to each voice port If a call comes in for (408) , the router needs to know that this telephone is connected to voice port 2/0/0 To hold this information, Cisco IOS software uses objects called dial peers

Step2 – Network (VoIP) Dial-Peers To route a call to the destination telephone over an IP network Commands used: destination-pattern session target

Example – West Router POTS Dial Peer config West(config)# dial-peer voice 401 pots West(config-dial-peer)# destination-pattern West(config-dial-peer)# port 2/0/0 West(config-dial-peer)# exit West(config)# dial-peer voice 402 pots West(config-dial-peer)# destination-pattern West(config-dial-peer)# port 2/0/1 West(config-dial-peer)# exit

West Router VoIP Dial-Peer West(config)# dial-peer voice 501 voip West(config-dial-peer)# destination-pattern West(config-dial-peer)# session target ipv4:
